Robert Hughes and Michael Hewitt, EPCAMR, “3D Modeling of Eastern Pennsylvani...Michael Hewitt, GISP
The complex geologic setting and historical mining of the anthracite mines creates a challenge to calculate the volume of water stored within the underground mines. EPCAMR’s recent mapping effort has reasonably found that almost 9 billion gallons of mine water resides in storage in 10 mines in the Southern Field and approximately 435 billion gallons in all the Northern Field. This associated report attempts to build on previous investigations to locate and quantify large volumes of water existing in underground mine voids, known as Mine Pools, in the Southern and Northern Anthracite Coal Fields of Eastern Pennsylvania. The goal of this project was to produce 3D Modeling of Eastern Pennsylvania Anthracite Mine Pools in Earthvision to Improve Water Quality Restoration and AMD Treatment via Consumptive Use Mitigation Projects in the Susquehanna River Basin. When pairing treatment with the ability to control the amount of water coming out of the mines, large flushes of stormwater that would normally escape untreated could be retained, later treated and released in times of low water or drought conditions.
Distribution of petroleum product within the oil rich Niger Delta area of Nigeria is a daunting
task because of its deltaic nature. To solve this challenge, fixed fuel dispensing stations will be built in the
coastal environment to receive and make supplies available to fishermen and marine transporters. Building of
such fuel stations require proper foundation design. Soil test results of the region was obtained and a foundation
design was made to ascertain the number of piles pile depth, pile spacing, skin friction, lateral load bearing
capacity and end bearing capacity. API codes where used to check and ensure that the results obtained are
within safety limits. This will ensure that the offshore structure completes it intended and designed life span.
There are seven identified prioritized abandoned mine sites: Philippine Pyrite Corporation - Bagacay, Hinabangan, Western Samar; Basay Mining Corporation - Brgy.

The Bagacay site, which was formerly worked for the recovery of pyrite/copper, is located at the border of a nature reserve. It exhibits many environmental problems, including the formation of Acid Mine Drainage (AMD) and the related spread to nature of potential toxic metals. MGB has conducted a preliminary investigation into the environmental impacts at Bagacay Mine and developed some initial rehabilitation plans including some revegetation trials. These plans are insufficient for final closure and rehabilitation but can be identified as interim remediation measures...

Photography and videography of the diversion areas.
6. THE FOREST (CONSERVATION) MAPS, BIODIVERSITY INDEXING, WILDLIFE IMPACT ASS...RavindraSaksena
The maps are integral part of the application for seeking "forest clearance" under Forest Conservation Act, 1980.
The application requires political map of the State, State Forest Cover Map, Map of wildlife protected areas and other areas under the international conventions, important bird areas, biosphere reserves, mineral maps of the district, forest stock maps, forest management maps, compartment histories, working plan prescriptions, biodiversity indexing, regeneration survey maps, wildlife activity areas, sites of compensatory afforestation, safety zones, Tiger and Elephant corridors, water bodies in the vicinity, archaeological sites or monuments, mineral reserves, coal seams, phase-wise felling planning, reclamation phase wise planning, etc.
The Government of India accord "forest clearance" for operation of all "non-forest activity" in forest areas under the Forest (Conservation) Act, 1980. Since wildlife is integral part of "forest areas", the impact of "non-forest' activity on wildlife is also assessed by the State Wildlife Boards and the Standing Committee of the National Wildlife Board.
The applicant seeking "wildlife clearance" under Section-38O(g), of Wildlife (Protection) Act, 1972 is required to submit proposal to Field Director or Divisional Forest Officer. The proposal is prepared after the "wildlife impact assessment" of the diversion area. The "wildlife habitat management plan" is prepared to mitigate the adverse impact of diversion area. Then this "wildlife proposal" is scrutinized at the level of Chief Wildlife Warden, State Government; State Wildlife Board and to the Standing Committee of the National Wildlife Board for final approval.
Central India is having "Tiger Reserves" and "Elephant Reserves" both. Even linear ancillary activities of mines - water hydro-structures, pipelines, transmission lines, tram lines, conveyor belts, coal handling plants, railway lines etc. adversely interact with the tiger and elephant corridors.
Thus "wildlife clearance" is necssary for operation of these mines.
All "deforestations or diversion" of forest areas including reserve forests, protected forests, unclassed forests, revenue forests, dictionary meaning of forests and DLC lands require "prior approval" under Section-2(ii) of Forest (Conservation) Act, 1980 from the Government of India. The State Governments are not having any power for this purpose.
The "mining leases" cannot be operate unless the "diversion order" has been obtained from the Ministry of Environment, Forests & Climate Change. The mining leases can be executed under the Mines & Minerals (Development & Regulation) Act, 1957; Coal Bearing (Special Provisions) Act, 2015 or transfer of old leases etc. all require prior sanction of the Government of India.
For submitting the technical and legal proposal, guidance has been provide to the greenfield project investors. The presentation shall shall be useful for the understanding of Forest (Conservation) Act, 1980.
3 THE INDIAN FOREST ACT, 1927 LAND MATTERS AND BLANKET NOTIFICATIONSRavindraSaksena
The reserve forest and protected forest and unclassed forests areas are defined under Indian Forest Act, 1927. The order dated 12th December, 1996 of the Hon'ble Supreme Court defines "forests of dictionary meaning". The various States are having different "definition" of "dictionary meaning of forests". During 19th Centuary different Provincial Governments and Princely State notified "forests under blanket notification" (without formal area specific notifications) - Thus understanding is must for smooth operation and legal compliance.
All proposals under Forest (Conservation) Act, 1980 require details of "forest crop", crown density, forest crop assessment Biodiversity Indexing, limitations of the satellite imageries for assessment
The subject of "forests and wildlife" are placed in the List-III, Concurrent List, Seventh Schedule of the Constitution of India. The Article-351 and 354 provides that the State Governments and State Assemblies cannot take any decision repugnant to the Central Acts.
All mining activities require "forest clearance" under the Forest (Conservation) Act, 1980; "environment clearance" under teh Environment Impact assessment Notification, 2006 (under revision) and "wildlife clearance" under Section-38O9g) of Wildlife (Protection) Act, 1972.
The forest areas are also impacted by Forest Rights Act, 2006 and Panchayati Raj Extension to Scheduled Areas Act, 1996.
Thus it is necessary to under the holistic "legal framework" to carry-out mining in forest areas.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

• Should having adequate prescriptions to take care of adverse
impact of mining on the site.
• The mine bock shall be protected against soil erosion, siltation of
adjoining water bodies by profuse deployment of Gabion
structures, retaining walls, geo-textiles to reduce soil erosion.
• With the passage of time (operation period 1 to 15 years) Gabion
structure shall be constructed on the vulnerable sides of the site to
stop any possible escape of overburden.
• The ultimate water body shall have depth of not more then 10
meters. The wall of this water body shall be strengthened by
“retaining walls”.
• The catchment area of this water body should be small.; thus there
would be no possibility of bursting of earthen dam even in
torrential rains. To take care of escape of silt an additional “Silt
Settling Pond” should be planned, to reduce probability of escape
of overburden.

Techniques of Sal Regeneration
The technique for Sal regeneration is available on these three counts:
A. Technique for direct seed sowing of Sal seeds have been
developed by J.P. Sharma et al (refer Indian Forester, 2004; the
Sal trees developed by this techniques can be seen at Ambikapur
nursery, Ramanujganj Road, Ambikapur, district Surguja, C.G.).
B. The technology of direct sowing of Sal seeds in polypot in nursery
is also available. The Korba Forests Division and certain private
coal mine operators have carried out Sal plantations in mined
out area of their mine.
C. Recently Jharkhand Forests Department has developed technique
for developing “Clonal Sal Seedlings”. This methodology is based
on the lines of Eucalyptus Clonal Seedlings. In this methodology
selected Sal trees are felled and allowed to develop coppice
shoots, then these coppice shoots are harvested and 3” to 4”
long cuttings are placed in polypots or root trainers for
development of roots along with application of rooting
hormone. This methodology has got success rate of about 40%.
63. Eco friendly approach
o Adherence to latest Eco-friendly technology – Surface Miner
o Phase-wise felling to reduce adverse ecological impact .
Transplanting of trees to reduce genetic losses.
o Sequential mining
o Transportation through belt conveyors.
o Scientific Void Management - Internal dumping will start after 3rd
year i.e. no external dumping from 4th year onwards with effective
top soil management.
o Effective Top soil Management
o Planned felling of trees & afforestation
o Progressive mine closure.
o Entire area shall be reclaimed with in lease period with formation
of multi-tier climax forest community.
o Landscape planning
